The claim
A positive antibody test can prove that you are immune to SARS-CoV-2, the novel coronavirus that causes COVID-19.
Original publisher’s rating
Uncertain. Antibodies in your blood show that your body has fought an infection caused by the novel coronavirus. But having a positive antibody test has not yet been proven to tell you with certainty that you are immune to being infected a second time.
